Event vs years Since Diagnosis
Description
Computes relative risks (RR) of second cancers over specified years-since-diagnosis intervals. SEER incidence rates are used to compute background/expected numbers of cases E, sex, age, and calendar year specifically. RR = O/E where O and E are the numbers of observed and expected cases.
Usage
esd(d,srfF,srfM,brkst=c(0,2,5),brksy=NULL) Arguments
d |
Input data.frame with columns: yrdx, agedx, sex, py at risk (in years), cancer1, and cancer2. Cancer1 and cancer2 should use standard SEERaBomb cancer names, see mapCancs. Cases not ending in a second cancer should have cancer2 set to "none". |
srfF |
Female incidence surface. Output D of mk2D for females, for cancers in cancer2 |
srfM |
Male incidence surface. Output D of mk2D for males, for cancers in cancer2 |
brkst |
Vector of breaks in years used to form times since diagnosis intervals/bins. |
brksy |
Vector of breaks of calendar years to show trends. Leave NULL for all in one. |
Value
data.frame with observed and expected cases, RR, and RR CI for each time since diagnosis interval.
Note
